CLAMP-AND KEY.PLATE DEVICE FOR FASTENING RAILS.

SPECIFICATION forming part of Letters Patent No. 788,502, dated April 25, 1905.

Application filed July 14, 1904. Serial No. 216,613.

Jo all whom, it may concern.

Be it known thatI, GEORGE ANDREW DEMA- REST, a citizen of the United States of America, residing at Berwick, in the parish of St.

Mary and State of Louisiana, have invented certain new and useful Improvements in Clamp and Key Plate Devices for Fastening Rails, of which the following is a specification, reference being had therein to the, accompanying drawings.

This invention relates to new and useful improvements in fastenings for rails; and the object of the invention is to provide an efiicient device of this character which will securely hold the rail to plates without the use of fish-plates commonly held by spikes to the ties of railways.

The invention consists'in various details of construction and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure l is a side elevation of my improved 2 5 fastening for rails. Fig. 2 is a cross-sectional view through a rail and the fastening apparatus therefor, and Fig. 3 is a top plan view of the apparatus.

Reference now being had to the details of 3 the drawings by numerals, 14L designates a rail of usual constructiom and 8 designates a plate which rests upon a tie. Said plate 8 is recessed, as at 9, upon its upper face for the reception of the heads 10 of the bolts 11,

which pass through apertures in said plate and tie and receive nuts which are adapted to be positioned in recesses in the under surface of the tie, whereby said plate may be securely held to the tie. A portion of the tie is recessed, as at 7, and the plate 8 has recesses through which the keys 3 and 6 are designed to pass. Said key 3 has a projection at its upper end adapted to overhang the flange 15 of the rail 14 and is recessed on its outer edge, while its lower end is inwardly turned and designed to engage the under surface of the plate 8. The second key 6 has a groove upon its inner edge adapted to register with the groove upon the outer edge of the key 3 to receive a locking pin or rivet 5, whereby 5 the two keys may be held together and in a locked relation with reference to the plate and rail. Each side of the rail is equipped with a similar construction of locking-keys, and

when it is desired to remove the rail the rivobserved that the use of fish-plates is dispensed with and also the employment of spikes,which 6 5 are driven into the ties which are commonly used, and in their place I provide the mechanism shown and described, in which it is not necessary to use nut-locks or fastening-bolts employed for holding the fish-plates to the rails.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A railway-rail fastening comprising, in combination with a tie, a plate mounted upon said tie, bolts securing said plate to the tie, keys engaging the opposite edges of the flange of a rail and the under surface of said plate,

a second key, a rivet passing through regis- 3O tering grooves in the contact edges of said keys, as set forth.

2. A railway-rail fastening comprising, in combination with a tie, a plate mounted on said tie, bolts having heads countersunken in 5 recesses in said plate and extending through said tie, nuts upon the bolts, a key having registering grooves in the adjacent edges of sa d keys, as set forth. IO

In testimony whereof I aflix my signature 1n laterallyprojecting portions adjacent to its ends, one of said projections adapted to overhang the flange of a rail and the other propresence of two Witnesses.

jection to extend underneath the bottom of GEO. ANDREW DEMAREST. said plate, the outer edge of said key having Witnesses: a groove, a second key passing through an 1 1 aperture in said plate, and a rivet engaging ALoNZo GILMORE, ALPHoNsE J. OUNEo.
